This paper presents the Constructed Wetland Model No1 (CWM1), a general model to describe biochemical transformation and degradation processes for organic matter, nitrogen and sulphur in subsurface flow constructed wetlands. The main objective of CWM1 is to predict effluent concentrations from constructed wetlands without predicting gaseous emissions. CWM1 describes aerobic, anoxic and anaerobic processes and is therefore applicable to both horizontal and vertical flow systems. 17 processes and 16 components (8 soluble and 8 particulate) are considered. CWM1 is based on the mathematical formulation as introduced by the IWA Activated Sludge Models (ASMs). It is important to note that besides the biokinetic model a number of other processes including porous media hydrodynamics, the influence of plants, the transport of particles/suspended matter to describe clogging processes, adsorption and desorption processes and physical re-aeration must be considered for the formulation of a full model for constructed wetlands.
本文介绍了人工湿地模型1（CWM1），这是一个用于描述潜流人工湿地中有机物、氮和硫的生化转化与降解过程的通用模型。CWM1的主要目标是预测人工湿地的出水浓度，而不预测气体排放。CWM1描述了好氧、缺氧和厌氧过程，因此适用于水平流和垂直流系统。该模型考虑了17个过程和16个组分（8个可溶组分和8个颗粒组分）。CWM1基于国际水协活性污泥模型（ASMs）引入的数学公式。需要注意的是，除了生物动力学模型外，为了构建完整的人工湿地模型，还必须考虑许多其他过程，包括多孔介质水动力学、植物的影响、用于描述堵塞过程的颗粒/悬浮物的输运、吸附和解吸过程以及物理复氧。
